$3/$5 $300 max. 6 handed (3 empty seats.)

My opponent and I both have around $450

Opponent is loosening up, and will float around light, but will fold pretty tight to serious money. He thinks I'm weak/passive/readable and he can control this table.

MPish limps
LP raises tp $10
I make it $40 from the SB with Aces
MP folds
LP calls because he's not going to let me push him around

~$85 in the pot, ~$350 behind

K84 rainbow

How are we getting maxium value here?
